mometer, at noon, just before arriving at El 
Buredgiat, and found the temperature equal to 
that of the former day; ninety degrees. This vil- 
lage is placed accurately inKanffer'^ map. We 
steered south-east and by south. Proceeding 
towards Nadir, the course altered, and we 
steered due east. The river here appeared like 
IV^ A non-descript shrubby species of Salsola, belonging to that 
division of the genus esWcA Siteda by Forshahl and Pallas, and dis- 
tinguished principally by the want of the membranaceous wing to 
the calyx. The species is very much branched, with the bark of 
an ash colour ; the smaller branches very leafy; the leaves two to 
three lines long, a little convex below ; the flowers are attended by 
three small bracts, and generally ternate, but are found also soli- 
tary; the seeds black and shining, very small. We have called 
it Salsola nitida. This was found in the neighbourhood oiRoseita.

v. A non-descript species of Wall-Jlower, (Cheiranthus Limi.) the 
short stems of which spread upon the ground, and seldom extend 
beyond the radical leaves ; these measure two and a half or three 
inches in length ; the flowers in loose racemes, with purple petals, 
broad and notched at the end, and interwoven with dark veins ; 
the pods compressed, an inch to an inch and a half in length, with 
a large three-cornered head, and thinly covered (like every part 
of the plant, the petals, stamens, and roots excepted) with white 
forky hairs. We have called it Cheirantiius humiiis. This 
grew in the neighbourhood of Rosetta. Cheiranthus pubescens, 
humilis , pilis dichotomis : foliis angustis ehngatis omnibus pinna- 
tifidis ; siliquis compressis, linearibtis, Iricuspidatis calycibutqite pu-
